ALBERT C. BUTLER, OF MINERAL WELLS, TEXAS.

BURNER.

To all tohom it may concern:

Be it known that I, ALBERT C. BUTLER, a citizen of the United States, residing at Mineral Wells, in the county of Palo Pinto and State of Texas, have invented a new and useful Burner; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful hydrocarbon burner apparatus and the ob ject of the invention is to provide a device of this design having an oil tank in which is arranged an inverted T-shaped pipe, the upper end of which is secured to the tank while the ends of the T project through the sides of the tank and are secured thereto.

A further object of the invention is to conduct a supply of air through this T-shaped pipe and project it above the level of the oil in the tank, whereby considerable pressure is obtained so as to force the oil through an opening in one portion of the T-shaped pipe and to the burner proper.

Another object of the invention is to provide a plug and packing in one portion of the T-shaped pipe in order to prevent the incoming air from reaching the oil proper.

Another object of the invention is to utilize a portion of the air above the level of the oil in order to spray the oil from the outlet orifice of the burner proper, in order that the combined air and oil may be projected into the fire-box (not shown) of a stove (not shown).

Further objects and combinations of parts will be hereinafter set forth and particularly pointed out in the appended claims.

Figure 1 is a diagrammatic view showing a number of hydro-carbon burners connected to the main air supply pipe. Fig. 2 is a side elevation partly in section of the hydro carbon apparatus, showing the same connected to a main air supply pipe, and Fig. 3 is a longitudinal vertical sectional view through the apparatus.

Referring to the annexed drawings, 1 denotes the main air supply pipe which in practice may be arranged in any suit-able locations throughout a town or city or other similar places. In practice this main air supply pipe is connected to a suitable air pump, of considerable air pressure, so that suificient amount of air Will be supplied to various points throughout the town or city.

Specification of Letters Patent.

Application filed November 24, 1909.

Serial No. 529,804.

As shown in the drawings, this main air supply pipe is tapped as a tube by means of the pipe 3. This pipe 3 is connected to the main air pipe by means of a suitable union 4.

5 designates an oil tank, in practice there being one located in every dwelling of a town or city. This oil tank has arranged therein an inverted T-shaped pipe 6. The inverted T-shaped pipe 6 comprises the vertical portion 7 and the two laterally extending portions 8 and 9, the portion 8 being threaded into a union 10, which union is connected to the vertical portion 7 by threads, as shown clearly in the drawings, while the portion 9 is also threaded in the opposite end of the union 10, as shown at 11. Disposed within the union 10 and adjacent to the end of the portion 9 is a plug 12 between which and a shoulder 13 of the union 10 a suitable packing 1 1 is disposed. By this construction, the air which is conveyed through the portion 8 is prevented from entering the portion 9 (through which the oil from the tank is conveyed). The pipe 3 is connected by suitable threads to the portion 8 of the T-shaped pipe. Connected to the portion 9 of the T-shaped pipe is a pipe 15 through which oil is conveyed to the burner proper 16, as shown clearly in the drawings.

The upper portion 7 of the T-shaped pipe is securely connected to the top of the tank as indicated at 17. Adjacent to the top of the tank the portion 7 is provided with an opening 18 from which the air from the portion 7 emanates so as to increase air pressure above the oil level.

The tank is provided upon its top with an opening 19 which is provided with a closure 20. This opening 19 is for the purpose of filling the tank with oil as its supply is decreased. Connected to the side 01": the tank as at 21 is a pipe 22 through which part of the air above the oil is conveyed to the burner proper 16.

The burner proper consists of two casings 23 and 24, the casing 23 having a hollow threaded portion 25 in which the threaded projecting portion 26 of the casing 24 is threaded. These casings are provided with valve seats 27 in which needle valves 28 cooperate, whereby the oil and air are con trolled. -The casing 23 is provided with an extension which has an orifice 29 through which the combined oil and air is projected in order to reach the firebox (not shown).

' and 03.

As the oil reaches this orifice, the air sprays the oil so that the same may be projected into the firebox. These casings are provided with downwardly extending portions 30 and 31 which are turned into elbows as at 32 The pipes 15 and 22 are connected to these elbows 32 and 33, as clearly shown, by means of threads. Each elbow is pro vided with a thumb screw whereby the pipes 15 and 22 are prevented from displacement. The lower portion of the oil tank is con ical so that the dregs and sediment of the oil will descend below the disposition of the portions 8 and 9 of the T-shaped pipe. In this way the sediment and dregs of the oil are prevented from entering the opening 3% of the portion 9. The lower end of the conical shaped portion has connected to it a pipe 35 in which a suitable valve 36 is' arranged. By the manipulation of this valve, the sediment and dregs may be drawn ofi' from the bottom of the tank. The pipe 3 is provided with a valve 37 whereby the air as it is conveyed through the pipe 3 may be controlled.

The tank or tanks, as shown in the drawings, are filled through the opening 19 with any suitable oil, after which air is forced through the pipe 3 and through the T- shaped pipe 6 up through the oil so that the air will emanate from the opening 18 of the portion 7 of the T-shaped pipe. hen the air reaches the space above the oil, considerable pressure is supplied above the oil, which forces the oil through the opening 34 of the portion 9 of the T-shaped pipe. The oil passes through the pipe 15 to the burner proper 16 and is sprayed by the air (which is conveyed through the pipe 22') and is projected into the firebox of the stove, not shown. The amount of air utilized in the space above the level of the oil for spraying the oil as it reaches the orifice of the burner proper may be increased or decreased by means of one of the needle valves.

From the foregoing, the essential features, elements and the operation of the device, together with the simplicity thereof, will be clearly apparent.

Having thus fully set forth the invention, what is claimed as new and useful is 1. In a hydrocarbon burner apparatus, an oil tank, a vertical pipe within the oil tank having an opening in its upper end, an air supply pipe connected to the tank and to the lower end of the vertical pipe, an oil delivering pipe connected to the lower part of the tank, an air delivering pipe connected to the upper end of the tank, and a burner having independent connections with the air and oil delivering pipes.

2. In a hydro-carbon burner apparatus, an oil tank having a T-shaped conduit arranged therein comprising a vertical portion and two lateral horizontal portions, means for connecting said portions, the vertical portion having an opening in its upper end for the discharge of air and one of the lateral portions having an oil inlet opening, and a plug closing communication between said lateral portions and the other lateral portion.

3. In a hydro-carbon burner apparatus, an oil tank having a T-shaped conduit arranged therein whereby air may be conveyed through the tank and projected above the level of the oil, said Tshaped conduit com prising a vertical portion and two lateral horizontal portions, means for connecting said portions together, one of said horizontal lateral portions having an opening therein through which the oil is forced to the burner, the two horizontal portions having arranged between them a plug to defiect the incoming air into the vertical portion whereby the same may reach the space above the level of the oil.
